livepeer: Enable network payments

[j0sh]

• Frontend sends api_key down with connect request (already in local storage). This Daydream key authenticates the payment request.

• Wire the API key through into the Livepeer SDK via start_lv2v

• Add knobs to configure the payment signer via LIVEPEER_SIGNER env var. If unset, default to signer.daydream.live. Disable with a falsy value.

• Send payments every 10s

• Smaller doc updates

LGTM - why every 10s for the payment? Is that arbitrary or part of the protocol?

It's arbitrary. Doesn't need to be too often, but shouldn't be foo far apart either. The timing can be tweaked however we like.
